GAS-HEATER.

To @ZZ whom, it may concern:

Be it known that I, CARL EICKEMEYER, a

n citizen of the United States, residing in Yonkers, in the county of Westchester and State of New York; have invented certain new and useful Improvements in Gas Heaters, of which the following is a specification.

This invention has reference to heaters such as used in living-rooms and the like, and has among its objects to provide a heater in which the gases of combustion are utilized to their fullest extent. i

Further objects of the invention are to provide improvedy means for permitting access of air to the burner without the Waste of heat therefrom and also to furnish a construction of heater in which the parts are assembled in such a manner as to be readily taken apart when necessary.

With these and other ends in vievsT the invention consists in a heater embodying the novel features, arrangements, and combinations of parts to be hereinafter described, and finally defined in the claims.

In the accompanying drawings, in which the same parts-are designated by corresponding reference characters throughout the several views, Figure 1 is a front elevation of a heater constructed in accordance with the invention. Fig. 2 is a top plan view of the same. Fig, 2EL is a detail perspective view showing the exhaust-compartment in the upper heat-box, the upper portion of the latter being removed. Fig. 2b is a vertical transverse section through the upper heat-box, taken on line 2b 2b, Fig. 2. Fig. 3 is a vertical longitudinal section taken on line 3 3 of Fig. 2. Fig. 4 is a vertical longitudinal section through the lower and upper plates of the upper andlower heat-boxes, respectively. Fig. 5 is a top plan-view of the heater having the upper portion or cover of the upper heatbox removed, and Fig. is a detail section showing the heat-fender plate below the bprner and the manner of mounting said p ate.

Referring to the drawings, a l) denote upper and lower heat-boxes, between which extend a number of radiator-tubes c and at one end a larger burner-tube d. The lower heatbox l) is provided with suitable legs upon which the heater is supported. It will be seen that the lower heat-box l) is made in superposed sections, the lower section e forming the main part of said box, while the upper section f constitutes the cover thereof. Thev cover or plate f is provided with a number of circular apertures f', arranged in two longitudinally-extending rows, and said apertures are provided with marginal seats, in which rest the lower ends of the radiator tubes or elements c. At one end the section f is provided with a comparatively large circular aperturefz, surrounded by a flange g, which is embraced by and forms a seat for the lower end of the burner-tube d. The sections c f are firmly clamped together by means of upright bolts h, the lower nuts of which form a tight closure and prevent the escape of water through the bolt-holes.

The upper heat-box a is constructed similarly to the lower heat-box-that is to say, it is constituted by superposed sections, the relation of which, however, is reversed. The lower section i is provided with a large circular opening i', registering with the burneropening in the lower heat-box and surrounded by aflange j similar to the flange g. About said flange fits the upper end of the burnertube d. The section or plate i is likewise provided with a number of-circular apertures i2, arranged in longitudinally-extending rows and registering with the openings f in the section f, and these apertures are surrounded by downwardly-extending flanges, about which fit the upper ends of the radiator lelements c. The upper section fv of the heatbox a constitutes the main portion of the same and corresponds with the section c, being united with the section i, by means of bolts lc, corresponding to the bolts h used in interclamping the lower sections. The upper section of the heat-box a is provided immediately above the burner-tube or iiue d with a removable lid Z, over which may be set cooking utensils and the like, which thus absorb the heat directly from the burner. At the opposite end of the section a an exhaustcompartment is provided, from which rises a collar or flange m for attachment to the smoke-pipe. Said exhaust compartment or chamber is constituted by upright walls n, arranged at right angles to each other in one corner of the box a, as shown best in Fig. 2a.

A burner 0 is arranged in the lower heatbox b immediately below the burner-fine d, and said burner is supplied with gas by means of pipes p, communicating therewith. Immediately below said burner the section e of the heat-box b is left open in order to permit an upward air-draft; but in order to retain the heat in the burner-tube and prevent IOO IIO

its escape in downward direction a circular render-plate g is arranged beneath said openlng, as shown in F ig. 6, being supported by means of a bracket r, similar to the bracket s, by means of which the burner o is supported. Said plate g is of substantially the same area as the opening beneath the burner, but is spaced downwardly, so that air can enter at the sides of the same, as indicated by the arrows in Fig; 6'.

Both of thehe'at-boxes a' l) are' provided between' the rows of radiator' elements with a longitudinal row of vertically-disposed airpassages t, by means ol which' the upward passage of th'e air through said heat-boxes and' between the radiator elements is afforded.

The whole structure described' is held together lirmly by means or bolts a, passing downwardly from' the upper heat box, through several of the radiator elements, and through the lower'heat-box, as shown in Fig. 3. The upper end of one of said bolts is supported a bracket u', arranged in' the exhaust-chamber, as shown in Fig.` 2b.

The operation of the improved heater'is as follows: The heat being generated in the burner-tube al, which is supplied withV airA at the sides of the fender-plate q, rises from said tube into th'e upper heat box or compartment a and is diffused throughout the' same. The hot air then passesdownwardly through alll the elements c and into the lower heat-box l), where it is likewise' diffused. Both boxes and all the radiator elements are thus filled with the hot gases of combustion, and substantially the entiresurface ol the heater radiates heat.v A draft is created inthe smokepipe' and the radiator element directly connected thereto, so that the hot gases are sucked downwardly into the lower heat-box and thence upwardly through the radiator element in communication with the exhaustcompartment, which element might be termed the exhaust element. After passing upwardly through said exhaust element the gases enter the exhaust-compartment (being prevented from re'ntering the box a by means of the partitions n) and pass upwardly into: the smoke-pipe, which is connected with the collar fm and preferably arranged to conduct the gases of combustion from the room, the entrance of said gases into the latter at any point being thus pre'- vented, so that the atmosphere will' not be vitiated.

Having thus described my invention,- I claim as new and desire to secure by Letters Patenth l. A heater comprising upperV and' lower heat-boxes, a burner-tube connecting the same, a burner arranged* in the lower portion of said burner-tube, a plurality of upright radiator tubes or elements likewise' connecting said heat-boxes, and partitions in said upper heat-box forming therein a single exhaustcompartment commun'icating'V directly' with only one of said elements, the hot gases passing through said last-named element in' upward direction, but through the other" elements in downward direction.l

2. In a heater, the combination of upper and lower heat-boxes, each made superposedI sections,bolts to intercl'amp the sections of each box, a burner'- tube connecting said boxes, radiator-tubes also connecting the same, and bolts passing vertically through the upper heat-box, certain of said radiator-tubes, andthe lower heat-box.

In testimony that I clainr the' 'foregoing' as my invention I have signed my name in presence of two subscribing witnesses.
